en.Wedoany.com Reported - Anhui Dongfang Electric Power Construction Co., Ltd. has successfully connected the 30MW/60MWh user-side energy storage station project, built for Anhui Huaertai Chemical Co., Ltd., to the grid for stable commercial operation over several months. Through customized solutions and engineering expertise, the project has achieved core objectives including peak shaving and valley filling, demand reduction, stable power supply assurance, and energy conservation and carbon reduction.
The 30MW/60MWh energy storage station of Anhui Huaertai Chemical Co., Ltd. is a key commercial and industrial energy storage demonstration project in the Dongzhi Economic Development Zone. Located within the Huaertai Chemical plant, it covers a total area of 4.5 mu (approximately 3,000 square meters) with a total building area of 3,000 square meters. The project is built upon the optimization and renovation of the existing plant distribution system, with overall coordination and one-stop delivery managed by Dongfang Electric. The solution maximizes the utilization of existing facilities, avoids redundant investment, and features a short implementation cycle, strong adaptability, and outstanding economic efficiency, meeting the continuous production needs and high-safety, high-reliability power upgrade requirements of chemical enterprises.
Targeting the characteristics of the chemical industry, such as high production loads, complex operating conditions, and high continuity of power consumption, the project provides a tailored energy storage solution. The solution adopts a lithium iron phosphate energy storage system, complemented by an upgraded intelligent EMS energy management platform. This precisely adapts to the production rhythm and load fluctuations of the chemical plant, enabling round-the-clock monitoring of power loads, intelligent scheduling of energy storage, equipment status assessment, and proactive fault warnings, thereby establishing a smart energy management system suited to the production pace of chemical enterprises.
The entire construction process adhered to high standards for power engineering and strict safety regulations for the chemical industry. From preliminary site surveys and solution customization, to standardized construction and quality safety control in the mid-phase, and finally to commissioning, grid connection acceptance, and full system integration testing in the later phase, every step was rigorously managed. Since the one-time grid connection and commissioning, all station equipment has operated with zero faults, zero anomalies, and zero safety hazards during normal operations.
Considering the continuous production patterns of chemical enterprises and regional electricity pricing policies, Dongfang Electric optimized the charging and discharging strategy during the solution design phase to maximize the value of peak-valley electricity price differences. The system automatically executes an intelligent mode of "storing electricity during valley periods and releasing energy during peak periods," replacing high-cost peak grid electricity. This effectively reduces the enterprise's monthly electricity bills and basic demand charges, alleviating the pressure of high electricity costs.
During the planning phase, the safety requirements of chemical production were fully considered, with provisions for power supply redundancy and emergency response capabilities. In the event of grid voltage fluctuations or sudden power outages, the energy storage system can achieve millisecond-level rapid response, switching to emergency power supply mode to ensure the stable operation of core production lines and precision process equipment, thereby avoiding risks such as production interruptions, process loss of control, and equipment damage.
To address issues such as large load fluctuations and concentrated peak loads in chemical production, the project employs an integrated system design. Leveraging the EMS platform, it enables real-time monitoring of power loads and flexible dynamic adjustment of charging and discharging, precisely smoothing peak load fluctuations. This prevents transformer overload or line overloading, continuously optimizes the operating conditions of distribution equipment, and extends the service life of critical power equipment.
As a core supporting project for the green transformation of the chemical enterprise, this energy storage project replaces traditional thermal power supply with clean electrochemical energy storage, reducing fossil energy consumption during peak hours and lowering the enterprise's carbon emissions and comprehensive energy consumption. The customized solution precisely meets the enterprise's needs for dual control of energy consumption, green factory creation, and low-carbon system certification, helping Huaertai Chemical optimize its energy structure and advance green and low-carbon upgrades.
Since its commissioning several months ago, Dongfang Electric has ensured the efficient and stable operation of the project through customized scenario solutions, high-quality system integration, standardized engineering construction, and refined long-term operation and maintenance. The project is well-suited for high-risk chemical production scenarios, maintaining zero faults, zero hazards, and zero accidents since operation; the energy storage utilization rate remains high, with a dedicated charging and discharging strategy deeply aligned with the continuous production rhythm of the chemical industry; peak shaving and valley filling effectively reduce peak power loads, optimizing the enterprise's power consumption structure; and it supports unattended fully automatic operation, reducing operation and maintenance costs.
User-side energy storage is an effective solution for high-energy-consuming industrial enterprises to optimize energy structures, reduce costs, ensure supply, and improve low-carbon efficiency. It is also a crucial support for the green transformation and safety quality improvement of the chemical industry. Dongfang Electric continues to focus on the new energy sector, providing one-stop overall system solutions for high-energy-consuming enterprises such as mining and chemical industries, covering areas including user-side energy storage, distributed new energy, and comprehensive energy services. In the future, the company will continuously iterate and optimize its full-chain service system, focusing on pain points in industrial scenarios such as chemical and manufacturing sectors. Through precise customized solutions, reliable system integration, high-standard project implementation, and full-cycle operation and maintenance support, it aims to create more benchmark demonstration projects, solve challenges for industrial enterprises in energy consumption management, power safety, energy saving and cost reduction, and low-carbon transformation, thereby empowering regional energy structure optimization and green, high-quality industrial development.
